Patent DE-2116960-A1 (DE)
Title: Plate type heat exchanger - having baffle inserts for 2-phase feed
IPC: F28D9/00
Filed: 1971-04-07
Abstract: 2-phase feed, partic. with high liq. to vapour ratios, into individual channels of plate heat exchangers with upward flow is reliably distributed evenly, so avoiding choking, by making the cross section of the side feed distributor large enough to ensure separation of vapour and liq. phases therein, and in addition fitting into such distributor throughout its length a vertical baffle plate close to the pass partition entry, so that a gap results at the top and the bottom between it and such baffle plate. Such baffle is so dimensioned, that a permanent liq. seal is created by the separated liq. phase to the lower space, which pref. is extended to include a box shaped space below the pass partition. In this way, vapour only passes through the top gas, and liq. only through the bottom gap into the respective spaces in front of the pass partition. Their even distribution is derived from appropriate gap heights, affecting the press. drop across them. Intimate mixing of the separated phases at the entry to the pass partition results from their impinging upon one another at velocities controlled by the gap widths.

Patent DE-2319758-A1 (DE)
Inventor: KLEIN HERBERT
IPC: G06F11/14
Filed: 1973-04-18
Abstract: 1467158 Data processing system SIEMENS AG 5 April 1974 [18 April 1973] 15304/74 Heading G4A In a data processing system including a plurality of magnetic tape units connected via one or more control units to a central unit where the tape units are such that following a power failure they must be reset before they can be controlled by the central unit, the central unit issues a RESET command to which the control unit(s) respond to reset the tape units, and to rewind any tape units which were operating when the failure occurred through a fixed distance or to a fixed marker, e.g. the tape leader. The tape units each include a manual switch to render them operative under control of the central unit which, following a power failure, issues a special command which is decoded to actuate selected switches remotely. The tape may then be rewound for a time determined by a monostable circuit which is reset if the tape leader is reached. Alternatively rewind operations may continue for a fixed number of sectors on the tape. To restart a record or replay operation the rewound tape is advanced until the block in which recording or replay was being performed at the occurrence of the fault is detected whereupon the operation restarts.
